Understood. In my case, a.RData and b.RData contain identical
variables/data, plus simulation outputs from separate runs. The codes
deliver what I need. Good to know the three lines work. Thank you.
You might also want to investigate saveRDS/readRDS. Those functions are
similar to save/load, but they only write a single variable and don't
write variable names, so you can do things like
saveRDS(x, "x.rds")
y <- readRDS("x.rds")
to read the value of x directly into y.

Hi all,
This is great. Again, here is what I need. I run two separate jobs (a.R
and b.R) with results (say regression outputs) going to a.RData and
b.RData. I like to put all results in one place (where I can retrieve
them in one place, ab.RData). The following codes do it (I am not sure
if line 2 is needed but I am happy). Thank you all.
load("a.RData")
save.image("ab.RData")
load("b.RData")
save.image("ab.RData")
That's the same as
load("a.RData")
load("b.RData")
save.image("ab.RData")
because the second saved image overwrites the first one. It'll be
okay if all the variable names are different in a.RData and b.RData,
but will lose values from a.RData if any of them have the same names
as objects in b.RData. See the link I posted earlier to avoid this.

Huh.
I may by completely wrong but you cannot do such "merging". .RData
files are AFAIK places where all objects from given session are stored.
However you could load each .RData file and save/export result (one
object).
BTW, what do you mean exactly by "combine/consolidate"?
And finally, post your questions in plain text not html, otherwise
they can be mangled.
Cheers

Subject: [R] Merging RData files
I ran two separate hours-long projects. Results of each were saved
to two
separate .RData files.
Content of each includes, among others, the following:
me se t p sig pc21.age
0.640 0.219 2.918 0.004 ***

Question: How can I combine/consolidate the two .RData files into one?
Thank you.
